Truecaller, the popular caller ID service has announced that it has opened up TrueSDK to millions of app developers via a globally accessible self-service portal. TrueSDK, which was released by the company early this year, enables registered third party apps to onboard users with their Truecaller profile and verified phone number.

The company claims that early access partners across industries are seeing over one-third of their sign-ups on their apps coming from TrueSDK, which has become a preferred app sign-up mechanism for a diverse set of brands and startups.

“With this positive momentum, we have now launched the TrueSDK self-service. We are democratizing the access to the TrueSDK to all app developers globally and can start accessing and using TrueSDK in their apps from the self-service developer portal,” said Priyam Bose, Director of Worldwide Developer Relations at Truecaller.

The TrueSDK kit can be used by any app to offer one touch sign up, update a user’s information, or verify the user’s phone number based identity in their mobile apps through the users’ consent.
